Royal assent to the Act of Uniformity

On 29 April 1559, Elizabeth I also granted royal assent to the Act of Uniformity, which mandated use of the 1559 Book of Common Prayer and formed the liturgical core of the Elizabethan Religious Settlement.[2][7] The act required attendance at parish church on Sundays and holy days and imposed fines on those who refused, seeking to create outward religious conformity despite ongoing doctrinal disagreements.

The Book of Common Prayer authorized by this act represented a compromise between more radical Protestant forms and traditional Catholic practices, retaining certain ceremonies and phrases while clearly rejecting doctrines such as transubstantiation.[2][14] By legislating a single, official form of worship, Elizabeth aimed to reduce the fractious religious divisions that had plagued England since the 1530s.

This measure was historically significant because it institutionalized a distinctive English Protestant identity that balanced reform with continuity. It also illustrated Elizabeth’s pragmatic approach: she prioritized political stability and national unity over doctrinal purity, insisting that subjects conform publicly while allowing some latitude in private belief.[7][11] For a woman exercising supreme authority in both civil and ecclesiastical spheres, enforcing uniform worship demonstrated her capacity to wield power in domains traditionally reserved for male rulers and clerics. The Act of Uniformity’s legacy can be traced in the enduring structures of Anglican worship and in broader debates about state control of religious practice.
